Water Pollution Control

Water Pollution Control

The Water Pollution Control Department operates a sanitary sewer system that includes a vast collection system and full scale, regional wastewater treatment plant located on 111 acres in Weathersfield Twp. Wastewater is conveyed to our facility via large capacity interceptor sewers ranging up to 48 inches in diameter and large capacity wastewater pumping stations located at seven strategic points in the system. The collection system consists of over 195 miles of interceptor and collector lines ranging in size from 6 inches to 48 inches, some of our sewers dating back to 1895. The sewer system currently serves over 15,300 customers in the City of Warren and many thousands more in the neighboring communities of Champion and Lordstown. Originally constructed in 1962, and upgraded in the 1980s, the wastewater treatment plant utilizes five primary settling tanks, four aeration tanks and four secondary clarifiers with a designed average flow capacity of 16 million gallons per day. The resulting effluent, (discharged water) consistently meets and exceeds EPA water quality standards. Our bio-solids handling facility produces Class A EQS bio-solids used by our local agricultural community as an economical earth friendly fertilizer.

Additionally, Water Pollution Control Department supervises and maintains the storm sewers within the City. This system consists of 138 miles of storm sewers, 241 miles of open ditches and over 5,500 catch basins. Our Storm Water Division strives daily to meet and exceed compliance with our National Pollutant Discharge Elimination System (NPDES) Storm Water permit. Beyond cleaning and maintaining the catch basins and sewers, we actively work to protect the Mahoning River from runoff pollution through education and enforcement of the appropriate regulations. 

Major projects undertaken by our department in recent years include:

  • Downtown sewer separation, which provided a storm sewer for the downtown area and prevents overloading of our sanitary system.
  • Upgrades and repairs to storm sewers in both the University St. and Country Club areas of the City, designed to prevent flooding.
  • Installation of a hydroelectric generator on our outfall to reduce energy consumption.
  • The rehabilitation of the Mahoning Interceptor, which services Champion and Northwest Warren to remove infiltration and inflow from this large diameter sewer.
